DUMP CAR.

Application filed. December 2 4, 1925. Serial No. 77,461.

My invention relates to improvements in dump cars.

It is an object of the invention to provide means for actuating doorwinding mechanismthro-ugh oscillations of a lever in such a manner thatthe actuating means will move in unison with the winding mechanism inone direction and move independently thereof in the opposite direction.

It is also an object of this invention to provide dump door raisingmechanism having locking means in conjunction with independent doorlatching mechanism so related to the raising mechanism, that the lockingmeans of the raising mechanism will be automatically released uponactuation of the latching mechanism to release the door.

Other and further objects ofthe invention will more fully and clearlyappear from the description and claims hereinafterfollowing.

In the drawings Figure 1 is a side elevational view of a portion of acar embodying my invention. 1 Fig. 2 is a vertical transverse sectionalView through a portion of the car as shown in Fig. 1; Fig. 3 is anelevational end view of the car; Fig. 4 is a fraginentary horizontalsectional view through a portion of the car above the outer end of thedoor raising and lockingmechanism, the section correspondingsubstantially to the line 4-a of Fig. 1. Fig. 5 is a horizontalsectional view through a portion of the car above the winding actuatingmechanism, and corresponding substantially to line 5 5 of Fig. 3. Fig. 6is an enlarged fragmentary side elevational view of one end portion ofthe car showing the door winding mechanism and pawl locking mechanismtherefor, together with the leverfor operating the latching mechanism.Fig. 7 is a vertical sectional view showing the door raising actuatingmechanism in inoperative position, the section being taken on a linecorresponding substantially to line 77 of Fig. 3. And

Fig. 8 is a view similar to Fig 7 but showing the door raising actuatingmechanism in its operative relation with respect to the ratchet wheel.

My invention is illustrated as applied to a car having vertical sidesAA, sloping end floors BB, center sill structure C, and dumping doors DD hinged to the center sill structure on the opposite sides thereof andadapted to extend outwardly to the car sides. Each side wall A includesside plate 10, top chord 11, bottom chord 12 and side stakes 13, thelatterbeing preferably of Z-shape formation. The center sill strue-.ture C includes channel shaped members 14.1t'having a sin-mounting ridge15, and; beneath the ridge are secured a number of hinge brackets asindicated at 16.

Inasmuch as the dumping doors, and mechanism therefor, on the respectivesides of the car are of similar construction, the description will beconfined to one sideof the car. Each dumping door is formed ofa platemember 17 flanged upwardly as at 18 beneath the sloping ridge of thecenter sill. Each dooris reinforced on its under side by a series ofhinge beams 19 formed at their inner ends with hinge eyes 20 adapted toreceive hinge pins 21, whereby thedoor is mounted upon the brackets 16.Eachdoor is reinforced longitudinally of-the car, ad jacent the rearedge thereof, by an angle member 22., and adjacent the free edge ofthedoor by a beam structure formed by a Z- shaped member and angle memberas indicated at 23 and 24 respectively. The hinge. beams 19 are extendedoutwardly ofthe free edge of the door through perforationsin the beams23 and 24. Pivoted 0n brackets 25 fixed to the side of. the car,adjacent each. floorbeam 19, are hooks 26, the lower'ends of which areadapted to engage beneath the outer projecting ends of the floor beams19 to support the door after it has been raised to, a substantiallyclosed position. The hooks are each formed with an upwardextension- 126,and the series of hook extensionsalong. the; side of the car areconnected by'a hori' zontal bar 27 which is adjust-ably connected at oneend by a link 28 to an operating and locking lever 29 supported on thecar struc: ture from a pivot disposed in fixed relation to the carstructure, as indicated at 30. -Adjacent the upper end of the-lever- 29there is provided on the car structure a bracket 31, on which ispivotallyv mounted a locking bar 32 to swing in the path of the saidlever- 29 to lock the same when the supporting hooks are in. latchingposition beneath the door.

As the doors are of considerable weight, power multiplying raising meansare pro-. vided to raise the doors to such aposition thatthe lower endsof thehooks 26may be brought into engagement with. the corree spondingfloor beams 19, and the door wedged to a closed position making a tightfit with the car side. In a preferred form the raising mechanismincludes two or more flexible members or chains 33 which pass oversuitable pulleys 34, which are rotatably mounted, as indicated at 35, insuitable brackets 36 and 37 respectively, said brackets preferablyresting on the lower chord 12 of the car side, and each of saidbracketsincluding an outer vertical wall 38 through which the pulleysupporting pivot 35 extends. The elements 33 are connected to the doors,and after passing over the pulleys 34, extend horizontally towards oneend of the car, and are adjustably secured to a bodily movable bar 38,as indicated at The bar 38 is guided and maintained in operativerelation at one end with the adjacent pulley 24 by a lip 40, which isdisposed above the adjacent element 33. The bar member 38 extendsthrough perforations in the vertical side stakes 13 and additionalguides are provided as indicated at 41 and 42 respectively, the guide 41being affixed directly to the car structure and guide 42 being formed asan integral extension of the bracket structure 37 For the purpose ofmoving the bar 38 longitudinally in order to raise the door a windingdevice, indicated at E, is provided, said device including a windingdrum 43 disposed substantially in alignment with the reciprocating bar38, and connected thereto by means of a flexible member or chain 44.(lo-operable with the drum 43, and preferably formed integrallytherewith, is a ratchet wheel member 45, with which is co-operable ahook shaped locking pawl 46, said pawl 46 being mounted on a bracket 47,and formed with a weighted arm or extension 48 which extends rearwardlyand has a laterally projecting lug 49 extending substantially in theplane of the door hook locking and operating lever 29. Co-operable withthe said lug 49 is a hook-shaped catch 50 which is pivotally mounted onthe lever 29 and formed with an abutment 150 adapt ed'to support thesaid catch 50 relatively to the lever 29 so that as the lever is movedrearwardly the catch will be in position to engage with the lug 49 ofthe said pawl 46, the end of the catch being bevelled as indicated at151 so that the latch is automatically displaced a suflicient amount topermit a recess 152 in the catch to engage the lug 49 and lock the pawl46 relatively to the lever 29.

The means for actuating the winding drum 43 by imparting a movement ofrotation thereto is indicated at F. Said actuating mechanism isconnected with the winding means E by means of a rotary shaft 51. theassembled mechanism presenting a wind less-like device journalled at oneend adjacent the side of the car in a bearing bracket 52 which in turnis carried by a gusset plate 53, the opposite or inner end of said shaftbeing journalled in a bearing bracket 54 carried by a supportingframework includ-. ing a vertical gusset member 55, which in turn issuitably supported by port ons of the framework of the car structure asindicated. at 56 and 57 respectively. The spacing of the windingmechanism E an appreciable distance from the actuating mechanism Fpermits the disposition of a ladder 111 therebetween without interferingwith the operation of the door operating device and also provides forsafe and convenient operation from the platform 110 of the car. Theactuating mechanism proper as indicated at F includes: a ratchet member58 fixedly mounted on the shaft 51; oscillatable arms 59-59 rotatablymounted on the opposite sides of said ratchet member; a detent member 60disposed between the arms 59-59 and pivotally mounted thereon asindicated at 61, said member 60 having a pallet 62 adapted to engagewith the teeth of the ratchet member 58; connections 63-63 pivoted tothe detent 60 at an appreciable distance from its pivot 61 as indicatedat 64; and a lever 65 pivoted to the car structure on a fixed pivot 66and also to the con nection 63, as indicated at 67, whereby rotation ofthe shaft 51 will be effected through a series of oscillations of thesaid lever 65 in a n'ianncr as will be described hereinafter. The pivot66 on which lever 65 is mounted is preferably in the form of a trunnionformed integrally with a bracket 68 secured to a fixed part of the carand mounted at an appreciable distance from the operating shaft 51. Saidtrunnion is perforated outwardly of the lever and a pin 65) is insertedtherein to retain the parts in operative relation. The lever 65 movesbetween guides 70 7O which maintain the lever against sidewise movementand also limit the for ward movement of the same.

The operation of the winding and actuating device is as follows:Assuming the door D to be open with the parts positioned as in Fig. 7,the operator moves the lever 65 in a clockwise direction therebyrotating the detent 60 until such. time as the pallet 62 is brought intoengagement with one of the teeth of the ratchet member 58 which willinduce interlocking action between the ratchet member 58, and theoscillatable members 59 (the parts then assuming the position shown inFig. 8). For the purpose of preventing undue strain on pivot 61 stops 71are provided on the inner face of oscillating members 59 which engagewith detent 66 when pallet 62 is in full engagement with itsco-operating tooth of the ratchet ,member 58, and thus limit the pivotalaction of dctent 6O relatively to the members 59. The

operator then continues the movement of the lever in a clockwisedirection to impart suflicient rotary movement to the shaft 51 so thatthe locking pawl 46 may be engagedwith the next succeeding tooth onratchet member 58, and thereafter he reverses the movement of lever 65,moving it in anti-clockwise direction, thereby rotating detent 60 in adirection to cause pallet 62 to move away from the teeth of ratchetWheel 58 and so permitting the oscillatablc members 59 to moveindependently of the ratchet wheel. Relative movement between detent 60and link 63 is limited by laterally projecting wings 160 formedintegrally with member 60 and which engage with link members 63. Theseoscillating operations of the lever .65 are successively repeated untilsuch time as the door D is substantially closed, atwhich time the lever29 operating the latches 26 is moved rearwardly until the latching hooks26 are well beneath the door beams 19, and thereafter the lock 32 isturned into the path of the lever 29 locking the same securely intoposition. As lever 29 is moved rearwardly to its locking position thelatch 50 in such a relation,

due to the wall 150 abutting against the edge of the lever 29, that thebevelled portion 151 will ride upon the lateral projection 49 of thelocking pawl permitting suflicient movement of the catch to enable thewalls of the recess 152 to interlock with the said projection 49.

Assuming that it is desired to discharge the load in the car with theparts in locked position as indicated in Fig. 6, the lock 32 is releasedand the lever 29 moved forwardly in a direction to move the supportinghooks 26 away from beneath the floor beams 19 of the door. As the lever29 moves to release the door the catch .50 moves in unison therewith,thereby disengaging pawl 46 from :the .ratchet wheel member 45 so thatthe drum is free to rotate in an unwinding direction and the door opensdue to the Weight of the lading thereon, as will be understood. In theopen position the weightof the doors is supported by suitable buffers 72and 73 which are preferably carried by the center sill structure.
